Drunken driving, sometimes called America's socially accepted form of murder, has become a national epidemic. Every hour of every day about three Americans on average are killed hydrunken drivers, adding up an incredible 350,000 over the past decade.A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American alcohol image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18 to 20-year-old drivers more than doubled, so the state recently upped it back to 21.Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes" about drinking and teach them to resist peer pressure to drink.Tough new laws have led to increased arrests and in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks.As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years' national prohibition of alcohol that began in 1919, which President Hoover called the"noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.The rule that only people above 21 years of age can drink__________.A.is a new law promoted by the twenty statesB.had been once adopted before the 1960sC.has been enforced since the prohibition of alcoholD.will be carried out all over the country

In spite of all stories of prosperity in the Unites States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate. Most acts of violence were committed by young people.57% of the criminals arrested in 1979 were youths below 25 of age. Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education, living within a settled home, being parent less, sufferings from other kinds of misfortune, etc. There are also other factors than material conditions which are responsible for the sharp increase of crime rate. In the first place, some state laws provide a death penalty but some not. Secondly, the Constitution allows every citizen to carry weapons for his own protection. It is therefore possible and easy for anyone in the country to get a gun. Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crime, the details of which are so accurately described that even children know how to duplicate what they have seen or read. All these have resulted in a high frequency of crimes committed both by professional criminals and by nonprofessional ones in murder, drug smuggling, robbery, etc. The author intends to tell the readers that_________.A. the United States is a wealthy country although poverty and crime exist thereB. crime has become a serious problem in the United States, although it is said to be a prosperous oneC. despite the fact that crimes have been increasing rapidly in the United States, it is a country of prosperityD. in spite of stories about poverty and crime in the United States, it is prospering at an increasing r
